Calamus Husk (Acorus calamus) Distillation Plant

A Calamus Husk (Acorus calamus) distillation plant is a specialized facility designed to extract essential oil from the dried husks and rhizomes of the Acorus calamus plant, commonly known as Sweet Flag. Calamus oil is prized for its sweet, woody, spicy, and earthy aroma and is widely used in perfumery, traditional medicine, and aromatherapy for its calming, digestive, and stimulant properties.

The extraction process primarily uses steam distillation, where cleaned and dried calamus husks or rhizomes are loaded into stainless steel distillation chambers. Steam is passed through the plant material, vaporizing the volatile aromatic compounds. These vapors are condensed, and the essential oil is separated from the water and plant residues. The oil is filtered and stored in airtight, dark containers to preserve its fragrance and therapeutic qualities.

Modern Calamus husk distillation plants are equipped with efficient steam boilers, corrosion-resistant distillation units, condensers, and oil separators, often with automated systems to precisely control temperature and pressure, optimizing oil yield and purity. The essential oil contains active compounds such as β-asarone, α-asarone, and camphene, which contribute to its characteristic aroma and medicinal effects. The plant follows stringent quality control and hygiene standards to produce high-quality calamus essential oil for use in pharmaceuticals, cosmetics, and wellness products.
